Invitation to a Master Class on Story-Telling on July 10 and 24

[Garrity, Dennis]

Dear colleagues,

 

Healthy Planet Action Coalition is convening a Masterclass in Story-Telling for HPAC members and

associated individuals to improve how we engage different target audiences when advocating climate action.

 

The course will be offered during two 1.5 hour Online sessions held on July 10 and July 24, 2025, both

are during our regularly-scheduled member meetings. The course is being led by Professor Jules Pretty,

an author and scientist, HPAC member and Emeritus Professor of Environment and Society at the

University of Essex. www.julespretty.com   For more information, see the attached document.

 

This is great way to make use of our member meetings in July and to build our skills on how to effectively

communicate our mission through good story-telling.  We hope to see you there.  Please confirm your

participation via an email to Dennis Garrity (d.ga...@cifor-icraf.org) with the title “Confirming

Participation in Masterclass”.

 

Please feel free to also invite your colleagues and friends to participate.

Here is a brief and inspiring piece on ‘What makes a good story?’

It’s well worth reading, whether or not you’ll be able to attend the Master Class.

Dear Colleagues,

 

The feedback from participants who attended the 1^st session of the Master Class on Story-Telling that

was convened on July 10^th was overwhelmingly positive. Deeply insightful. Practical. Applicable tools.

 

This was very encouraging, and a tribute to the brilliant ability of our master class guide, Jules Pretty.

 

The 2^nd and final session of the Master Class is scheduled for Thursday, July 24^th at 5.30 pm EDT. We look

forward to seeing everyone there once again to complete the short course on story-telling.

Dear colleagues,

 

Our next biweekly session of the Healthy Planet Action Coalition is on Thursday, August 7^th at 5.30 pm EDT.

The Zoom link is our usual one: https://us02web.zoom.us/j/88954851189?pwd=WVZoeTBnN3kyZFoyLzYxZ1JNbDFPUT09

 

The format will be an open discussion of key developments related to our mission.

 

Members are invited to introduce topics of interest. Some examples are:

 

• Reflections on the recent Arctic Repair and Tipping Point conferences
• Reflections on The Master Class on Story-Telling
• Discussion of the upcoming HPAC global online conference on the global heating emergency and preventing 2 degrees

Please feel free to also invite your colleagues and friends to participate.

  

With best regards,

[Garrity, Dennis]

Dear colleagues,

 

Our next biweekly session of the Healthy Planet Action Coalition is on Thursday, August 21^st at 5.30 pm Eastern Daylight Time (US).

We will be joined by Brian Soden, a former student of Tom Goreau, who will share his reflections on his recent research paper on a potentially more efficient alternative to stratospheric aerosol injection with SO2 or other reflective aerosols.

 

This method deploys absorptive aerosols like black carbon in the upper stratosphere. Climate models indicate that this new approach can reduce global temperatures an order of magnitude more efficiently per unit aerosol mass than conventional scattering-based interventions. 

 

The abstract of the paper and a link to the full paper is below.

 

Please feel free to also invite your colleagues and friends to participate.

Abstract

 

Stratospheric aerosol injection is a proposed method for offsetting greenhouse gas-induced warming by introducing scattering aerosols into the lower stratosphere to reflect sunlight. Here we explore a potentially more efficient alternative: weakening the Earth’s greenhouse effect by deploying absorptive aerosols in the upper stratosphere (~10 hPa). These aerosols warm the carbon dioxide emission level—where outgoing longwave radiation is most sensitive to temperature—thereby enhancing top-of-atmosphere infrared emission without altering atmospheric carbon dioxide concentrations. Idealized climate model simulations indicate that this approach can reduce global temperatures an order of magnitude more efficiently per unit aerosol mass than conventional scattering-based interventions. Although based on simplified model experiments lacking interactive aerosol processes and operational constraints, our results identify a distinct physical mechanism for climate intervention, arguing for further research into the impacts—especially potential unintended side effects—of injecting absorptive aerosols into the upper stratosphere as an alternative solar radiation management strategy.
